Malware causes intentional harm, direct or indirect, to the computer by damaging files etc. or to the user by stealing sensitive information of the user from the computer etc. A … Read more
Motherboard: A motherboard is a printed circuit board (PCB) that holds other modular devices, both required and additional, and facilitate communication among the devices to actually have the computer be functional. Motherboard is like a backbone to a computer system. Components like CPU, RAM, Harddisks along with additional devices like TV Cards, graphics etc. all … Read more
Control unit co-ordinates the transfer of data between registers of CPU or microprocessor and ALU. Control unit serves the instructions for ALU. Along with this, control unit, as its name implies, controls every other parts of the machine, their co-ordinations, traffic etc.
Arithmetic and Logic Unit (ALU): Arithmetic and Logic Unit is a like a calculator to a computer. ALU performs all arithmetic operations along with decision making functions. In modern CPU or Microprocessors, there can be more than one integrated ALU to speed up arithmetical and logical operations, such as; integer unit, floating point unit etc. … Read more
A type of computer processors that incorporates the functions of a computer’s center processing unit (CPU) onto a single integrated circuit is called a microprocessor. A microprocessor is a VLSI (Very Large Scale Integration) Silicon Chip. Microprocessor accepts digital or binary data, processes it according to instructions stored in it’s memory and provides results as output.
CPU (Central Processing Unit) in computer: CPU or central processing unit in computer is an electronic circuitry that carries out the instruction given by a computer program. CPU in computer execute instruction by performing basic arithmetic, logical, control and I/O operations as required per instruction. CPU in computer is considered to be the brain of … Read more
Computer systems reached today’s modern age step by step, these steps are called generations. In each generation computers with new features and functions starts to get the market and the older computers slowly gets replaced. IBM company started categorize the development of computers into generations, though not everyone in the industry including users will be agree on the periods of each generation. However, based on the use of electronic devices, computers systems can be categorized into following generations so far.
An analog computer is a form of computer that uses the continuously changeable aspects of physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved. As an analog computer does not use discrete values, but rather continuous values, processes cannot be reliably repeated with exact equivalence.
A computer is a multipurpose electronic device that can receive, store, process data and deliver information. A computer takes data such as numbers, text, images etc. as input and then process those data and converts those to useful information. Additionally, a computer can also store data and information both for future use. Also, a computer can perform scheduled tasks. Computers are programmed devices. Computer programmers write programs or software for computer which actually takes input, process it and outputs information.
